A magnetic levitation magneto-electric bicycle wheel hub comprises a hub (1), two hub shell covers (2), a flywheel (3), and a catch plate (15). The flywheel (3) and the catch plate (15) are carried on the two hub shell covers (2). A stator shaft (4) with a spline on its middle part is set in the hole of the two hub shell covers (2), a stator (5) is mounted on the stator shaft (4) by the spline. Six coils (6) are enwinded in the grooves which are set in the stator (5). Magnets (7) are affixed on the excircle of the stator (5). Two electric generators (14) are installed in the axisymmetric holes of the stator (5). A gear mounted plate (9) is disposed on the stator shaft (4), the gear mounted plate (9) which is screwed into the stator (5) has two drive gear sets, a small wheel gear (11) and a big wheel gear (12). Many magnets (8) arranged in a ring shape are affixed on the inner circumference of the hub (1). The coils (6) are connected in parallel with the two electric generators (14). The present bicycle wheel hub has a improved hub running speed, and the bicycle achieves greater traveling speed. |
